I have been using Cura with my Wanhao Duplicator 3 since 14.03. I tend not to bother updating too often as it all seems to work extremely well for me but I will try new version as and when the desire hits me.
At some unknown time in the last few weeks I cannot get it to slice if I have the "Machine centre 0,0" ticked in machine settings. If I untick that then all works as it should but when I tick it then it will not slice.
If I run from teh command line I get a Python error so I am thinking that it is something else that I have installed or modified since I last used Cura. I have tried 14.02 - .04, they are all the same. I have to fix this or I am restricted to positioning things at the front left in Cura and having them print rear right on the machine.
Command line output:
